CAR-COUPLlNe.

SPECIFICATION forming part of Letters Patent No. 494,736, dated April 4,1893.

Application iiled August l5, 1392.

To all whont t may concern:

Be it known that we, OHRLES H. DALE and FRANK A. FOX, both of the cityof New York, county and State of New York, have invented a certain newand useful Improvement in Car- Couplers, of which the following is aspecification.

Te will describe a car coupler embodying our invention and then pointout the novel features in the claims.

In the accompanying drawings Figurel is a horizontal view, partly insection, of acoupler embodying our invention. Fig. 2 is a verticallongitudinal section. Fig. 3 is a transverse section on the line 3, 3,of Fig. 1. Fig. 4 is a section of a certain part on the line 4, 4 Fig.l. Fig. 5 is a perspective view of an operating device.

Referring by letter to the drawings, A designates a coupler head. Asshown, it is bifurcated at its forward extremity. lt has a shank or bara. which may be fastened to a car in the usual manner.

B designates a knuckle. It consists of an elbow lever fulcrumed at itsangle by a pin b to the bifurcate extremities of the coupler head. 'Theouter portion of the knuckle B may be forked, so that an ordinarycoupling link may be inserted within it, and it is provided with holesfor the reception of an ordinary coupling pin. The inner part of theknuckle is shown as tapering toward its eX- tremity, and the end of thisinner part is rounded as at a", the object of thus rounding theextremity being to enable it to automatically force back a dog or blockD by which the knuckle is to be retained in a locked position. The dogor block D extends upward from a rock-shaft D. The rock-shaft D has abearing at one end in a projection a2 formed in the coupling head, andis supported at the other end by passing through and fitting a hole inthe side of the head. The outer end of the rock-shaft is provided withan arm CZ whereby it may be rocked. The arm d extends at substantiallyright angles to the dog or block D and serves as a counter-balance toreturn the said dog or block to a normal position, which, as here shown,is substantially vertical. The dog or block D at its upper end may movebetween two projections a3, a4,

in the coupler head, whereby it is sustained against lateral strain. Itwill be seen that when the knuckle is swung to a closed position therounded portion a will force the dog or block D rearward and allow theend of the inner portion of the knuckle to pass beyond it when the dogor block will resume its normal position and lock the knuckle. Obviouslyby pulling the arm d upward, by means of a chain or otherwise, the dogor block will be rocked backward out of contact with the knuckle so thatsaid knuckle maybe swung open.

Ve provide means for swinging the knuckle open during a movement of thedog or block D. This means, as here shown, consists of a link E having apivotal connection with the knuckle adjacent the pin b and at its otherend having a lost motion connection directly with the dog or block D.The link passes loosely through a vertically elongated hole e in theupper portion of the dog or block and at its end it is provided with astop or bulb e to prevent the dog or block from disengaging itself fromthe link. It will be seen that the stop or bulb e is beyond the end ofthe inner portion of the knuckle and that the dog or block will notengage with said stop or bulb until the dog or block is forced from theknuckle. In operation the dog or block will be moved along the linkuntil the knuckle is freed then a further movement of the dog will causeit to engage with the stop or bulb e and draw the link longitudinally toswing the knuckle open.

By connecting the link directly with the dog or block we can make therock shaft quite short as its portion within the coupler head need onlycarry the dog or block.
